In December 2007, ETSC published a PIN Flash concerning roads safety of motorcyclists. In 2006 at least 6200 Powered Two-Wheeler (PTW) riders were killed in road crashes in the EU representing 16% of the total number of road deaths while accounting for only 2% of the total kilometres driven. Norway, Switzerland, Denmark and Finland are the least dangerous places to ride, with average rider deaths between 30 and 45 per billion kilometres. While Greece, among other countries, is just below the EU average of 86 riders killed per billion km.
